Type-species: Davmata neka Dworakowska, 1979 , original designation

Diagnosis. Body form resembles Tautoneura Anufriev : tiny, length 1.8mm to 2.1mm, pale to yellow-whitish. Vertex produced medially, head almost as wide as pronotum, coronal suture present. Face slightly convex in profile, anteclypeus broad. Pronotum in mid-length shorter than twice length of vertex. Fore wing with spots and patches, 3rd apical cell broad, 4th apical cell shorter than half length of 3rd; AA vein absent. Hind wing venation as usual in Erythroneurini , subcostal vein absent.

Abdominal apodemes narrow and long.

Anal tube without appendages. Genital capsule weakly sclerotized. Pygofer side rounded, with several macrosetae at lower basal angle and numerous gracile microsetae on ventral half of lobe; pygofer dorsal appendages well sclerotized, articulated to pygofer side. Subgenital plate slightly exceeding pygofer side, broadened subbasally, apical part narrowed and curved outwards; with row of several submarginal macrosetae and row of thickened marginal microsetae on middle part, some rigid microsetae and some small, stout microsetae at apex. Style varying between new species and type species, preapical lobe distinct, with sensory pits or papillae. Connective with central lobe. Aedeagal shaft asymmetrical, situated on a short manubrium; gonopore subapical and ventral.

Note. Discovery of the new species described below, in which the male style is significantly different from that of the type species, suggests that interspecific variation in the style in Davmata parallels that of the related genus Tautoneura .
